Question

I need help please!!! thank you so much to the person who is going to help me.

Answer 1

5x-3
When parentheses are open you get 2x+5+3x-8
Because both parts with x are positive we add them together and get
5x+5-8
+5-8
Is the same as -3 because when you add 5 to -8 you are making the number greater
Hence you get 5x-3

Answer 2

5x - 3

Explanation:

Subtract the numbers

(2x+5) + (3x-8) ----> 2x-3 +3x

Combine like terms

2x-3 + 3x ----> 5x - 3

Answer

5x - 3

done! :)
